Bug Fixes

  • Contingency Analysis: When setting up a contingency analysis run for processing, PowerWorld performs an initial power flow solution to make sure the initial case is solved. Under most power flow solutions, there is also an initial pre-processing step that looks to do things like get a good initial guess for voltages and newly energized buses. This pre-processing step was missing in that initial contingency analyisi power flow solution on the base case. As a result under some circumstances if you had not solved the power flow BEFORE running contingency analysis, the initial contingency power flow may not solve when a normal Single Solution would have solved fine. This has been fixed.
  • Transient Stability: Fixed a bug with Distributed Transient that resulted in the automatically created plot image file not being returned.
